Detailed Description

Frequency domain high pass.

This filter only works on an image after it has been converted to frequency domain by a vtkImageFFT filter. A vtkImageRFFT filter can be used to convert the output back into the spatial domain. vtkImageButterworthHighPass the frequency components around 0 are attenuated. Input and output are in doubles, with two components (complex numbers). out(i, j) = 1 / (1 + pow(CutOff/Freq(i,j), 2*Order));

Member Function Documentation

static vtkImageButterworthHighPass* vtkImageButterworthHighPass::New  )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkAlgorithm.

virtual const char* vtkImageButterworthHighPass::GetClassName  )  [virtual]

Reimplemented from vtkThreadedImageAlgorithm.

static int vtkImageButterworthHighPass::IsTypeOf const char *  type  )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkThreadedImageAlgorithm.

virtual int vtkImageButterworthHighPass::IsA const char *  type  )  [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.
